Abstract (en)

[origin: EP4098651A1] The present invention relates to a process for preparing benzoprostacyclin analogues such as e.g. beraprost (4-((1 RS ,2 RS ,3a SR ,8b SR )-2-hydroxy-1-((3 SR , E )-3-hydroxy-4-methyloct-1-en-6-yn-1-yl)-2,3,3a,8b-tetrahydro-1 H -cyclopenta[ b ]benzofuran-5-yl)butanoic acid)starting from cyclopentenone intermediates e.g. of formula I in racemic or optically enriched formsuch as e.g. 2-(3-bromo-2-fluorophenyl)-4-hydroxycyclopent-2-enoneBeraprost and its enantiomerically pure beraprost-314d stereoisomer are pharmacologically active compounds for the treatment of pulmonary hypertension and vascular diseases.
